Accessories We offer all the available options and accessories that can be used on casters and wheels. All types of brakes, swivel locks, floor locks, bearings, axles, spanner bushings, thread guards, retaining washers, swivel raceway seals, quick change caster pads and plates, and heavy-duty swivel turntables.

To determine the load capacity you will need for each caster or wheel, divide the total weight to be moved by the number of casters or wheels.

Total Load ÷ Casters or Wheels on Cart

= Minimum Load Capacity Per Caster or Wheel

However sometimes we divide the total load by a factor of 3 if you are using four casters to ensure you more than enough safety and capacity built into your design. Sometimes floors are uneven or you may have an unevenly distributed live load and need the extra capacity to spare. Also you need to take into consideration the caster pattern for your design. Most common is two rigid casters on one end of each corner and two swivel casters on the other end rof each corner. Or you can have all four swivel casters in the corners. Another caster pattern is the diamond style where you have two rigid casters in the middle of the cart and one swivel caster in the middle of each end of the cart. This allows 360 degree rotation. You can also do this same style with two rigid casters in the middle and a swivel caster in each corner so you have six total casters under the cart. This allows for greater capacity and 360 degree rotation and stability so the cart will not flip.

Ratings are based on intermittent usage over smooth floors at a speed of up to 2.5 mph. (Heavy loads moved at high speeds can cause the bonding agent that holds the tire on the wheel center to break down.)

Caution: If you have an application where the cart is moved mechanically (tow motor, tow line, tug cart, forklift, etc.) you should use a kingpinless caster. This is because the shock loading on these casters can exceed the maximum capacity and cause premature kingpin failure if a swivel caster with kingpin is used.

Safety and Ergonomics:

While many factors need to be considered, you can reduce work related injuries and maximize productivity and efficiency by following these tips:

Select the largest practical wheel diameter and anti-friction bearings your application will permit

The larger the wheel diameter, the easier it will roll

Wheels with anti-friction bearings (tapered, ball, or roller) roll easier than wheels with a plain bore or delrin bearings

Operating Conditions:

Each wheel has unique physical properties which need to be considered for specific applications.

Consider these factors when selecting a caster or wheel:

Are shock loads, impact, or abuse likely

How will the equipment be moved, mechanically or manually

What speed will it be rolling

Will the caster or wheel come into contact with oil/grease, water, chemicals

What is the condition of the floor surface

Will they be rolling over debris, floor joints, etc.​

Extreme Conditions:

We have wheels capable of withstanding temperatures ranging from -50°F to 1,300°F. We offer both high temperature and low temperature grease.

Floor Protection:

The floor type and condition that the wheel will be rolling on must be considered to determine the proper wheel for your application. Repetitive rolling over the same path with wheels having a hard surface will eventually wear the surface of even concrete floors. Protection of hardwood floors in homes or gymnasiums will require wheels with soft non-marking rubber tread tires. Often times these soft rubber treads will not offer the needed capacity and wheels with polyurethane treads will be needed. We can help you select the right wheel for your specific application.

Cost Efficiency:

Let us help you insure longer caster/wheel life and maximum productivity by assisting you in selecting the right casters and wheels for your specific application. The right choice can help avoid down time and early replacement.
